The best course of action for the information security manager to support the initiative of leveraging popular social network platforms to promote the organization's products and services is to assess the security risk associated with the use of social networks. Security risk assessment is a process of identifying, analyzing, and evaluating the potential threats and vulnerabilities that may affect the confidentiality, integrity, and availability of information assets and systems. By conducting a security risk assessment, the information security manager can provide valuable input to the decision-making process regarding the benefits and costs of using social networks, as well as the appropriate security controls and mitigation strategies to reduce the risk to an acceptable level. The other options are not the best course of action, although they may be part of the security risk management process. Establishing processes to publish content on social networks is an operational task that should be performed after assessing the security risk and implementing the necessary controls. Conducting vulnerability assessments on social network platforms is a technical activity that may not be feasible or effective, as the organization does not have control over the platforms' infrastructure and configuration. Developing security controls for the use of social networks is a preventive measure that should be based on the results of the security risk assessment and aligned with the organization's risk appetite and tolerance

The greatest benefit of information asset classification is providing a basis for imple-menting a need-to-know policy. Information asset classification is a process of catego-rizing information based on its level of sensitivity and importance, and applying appro-priate security controls based on the level of risk associated with that information1. A need-to-know policy is a principle that states that access to information should be granted only to those individuals who require it to perform their official duties or tasks2. The purpose of a need-to-know policy is to limit the exposure of sensitive information to unauthorized or unnecessary parties, and to reduce the risk of data breaches, leaks, or misuse. Information asset classification provides a basis for implementing a need-to-know policy by:
* Defining the value and protection requirements of different types of information
* Labeling the information with the appropriate classification level, such as public, internal, confidential, secret, or top secret
* Establishing the roles and responsibilities of information owners, custodians, and users
* Enforcing access controls and encryption for the information
* Documenting the security policies and procedures for the information By providing a basis for implementing a need-to-know policy, information asset classi-fication can help organizations to protect their sensitive information, comply with rele-vant laws and regulations, and achieve their business objectives. The other options are not the greatest benefits of information asset classification. Helping to determine the recovery point objective (RPO) is not a benefit, but rather a consequence of applying security controls based on the classification level. RPO is the acceptable amount of data loss in case of a disruption3. Supporting segregation of duties is not a benefit, but rather a prerequisite for implementing a need-to-know policy. Segregation of duties is a principle that states that no single individual should have control over two or more phases of a business process or transaction that are susceptible to errors or fraud4. De-fining resource ownership is not a benefit, but rather a component of information asset classification. Resource ownership is the assignment of accountability and authority for an information asset to an individual or a group5.
